PUMPING SYSTEM.

Specification of Letters Patent.

Patented Mar. 1a, rare.

Application filed May 23, 1910. Serial No. 563,032.

,plying water under pressure to the ma s from separated wells, will avoid the expense required for plants to effect two or more separate pumpings, will enable large trunk mains to be dispensed with, with the consequent saving of expense of construction and reduction of friction, will enable the pres sure to be increased at any particular point where most needed and will enable the utilization of segregated units of source, such as wells, without interference in the flow from the respective wells.

To these ends, my invention consists, generally stated, in a system comprising pumping means for lifting the water from the well and forcing it under pressure from the point to which it is raised directly to distributing means such as mains, tanks, or reservoirs, in a continuous flow and by a single operation from suitable motor means.

This invention is embodied in the combination of the elements of a water-lifting well pump, with force pump elements in direct communication with the well-pump elements and exerting pressure on the water to force it out to distributing means under pressure, such receiving and distributing means being in direct communication with the forcing-pump elements and common m0 tor means for driving both the "well pump elements and the .force pump elements. The lifting pump and the forcing and pressure imparting pump may be embodied in a single pump-structure or in two separate devices.

In water works systems where wells are used as a source of supply, great difficulty is experienced on account of the flow of one well interfering with that of another. Consequently a system of pumping which will permit of the segregation of the wells is essential to the successful utilization of a plurality of such units of supply. In all the systems of pumping so-far devised, even although a number of wells have been placed in different localities, still they must be in comparatively close proximity, so as to be pumped from a central pumping station. Segregation of the wells would obviate the use of large trunk lines of mains, would increase the pressure at the point where it was most needed and would nec'essarilv reduce the friction of the water in the pipes to a minimum. Up to the present time, so far as I am aware, no system has been proposed which would admit of utility in accomplishing this end. My system permits of the wells being bored as far apart as is desired so as not to interfere at all, the water put into the mains under the required pressure and the expense of building large plants done away with, inasmuch as the power may be electric, gas engine, gasolene or otherwise and the whole pumping outfit may be placed under a street, side-walk, or lot, obviating the necessity of building house or plant.

In the experiment I .have made, a 10 well was bored under the street and a chamber dug out about 10x18. Into this was placed the pumping outfit. As the pumping means are run by an electric motor, only a wire goes into the chamber. A concrete cover is put over the street and no obstruc tion is offered by the mechanism and a surface struoture for housing obviated. All other advantage in this form of pumping is that it does not require constant attention,

one man being able to look after from a half dozen to a dozen pumps, inasmuch as his duties are principally watching the lubrication. With my invention water is pumped from wells of any depth into mains under the required pressure, without the use of pumping stations, or reservoirs employed forthe purpose of obtaining a required head of water. From the fact that pumping stations do not have to be built, large, mains are made unnecessary and, the attendance upon the pumping being so slight-and the water only having to be pumped once, the price of the water put into the main is reduced to a minimum, which is very essential where water is sold.

The preferred forms of embodiment of my invention are illustrated in the accompanying drawings in which- Figure 1 is a side view in elevation, partly broken away, of the pumping system, and showing a motor, a well pump 'and a rotary force pump combined; Fi 2, a modified form of the invention in wh1ch a centrifugal force: pump is employed in .connection'with the well pump and motor; Fig. 3, a side Viewv in elevation ofa series of sources and pumping units, adapted. for. a system when a plurality 'of properly segregated wells is resure force pump shown insaid view and also showin the main-driving shaft and gear connectlon with the pump, and. Fig. 5,

a detail vertical section of the centrifugal pressure force-pump shown in Fig. 2.

Referring to'the drawings, 1 designate a well casing into which extends an ordinary lift or impeller pump, the form shown,

consisting of a screw pumpi2, which is"- driven by bevel gears 3 and 4. The gear 4 .is carried by a shaft 5 mounted in suitable bearings 6 which are supported ona suitable masonry foundation 7 On this. foundation is also mounted a force pump 8,

which maybe of any desired type adapted pres-I orce for forcihgthe water therefrom under sure and is shown as of theordinary pump class. A connecting pipe 9 leads from the top of thewell to the force pump providing a direct and continuous communicationbetween said parts. 'A delivery main 1O communicates directly with the force pipes, reservoir or other distributing means.

A motor device 11, common .to both pumps, consisting preferably of an electric motor although a ga'solene or steam engine may be employed, is mounted on the foundation, preferably between the twopumps. v I The shaft -12 of this-motor at one end' has a gear 13 meshing-with and driving a speed-' reducing gear '14 on'tlie shaft 15 of the force pump and atthe other endvhas aconnection 16, -consisting preferably of a flexible coupling engaging the shaft 5 of the lift pump 2. By this arrangement the two pumps are synchronously driven by the same operation so that the supply of water pumped from the well and forced from the force pump'may accord andthe flow from well to force pump be continuous and'so that water not under pressure will be delivered from the lift-pumpto' the forcepump andpressure imparted thereto by the latter and'the water pumped therefrom into the mains under pressuresuflicient for ser vice delivery at the required head.

A regulating waste pipe 17 having a closed upper end rises from. the connecting pipe 9, the function of whichis upon any stoppage of the force pump, to automatically stop the feed of the well pump by the pressure of an accumulated column of water therein on the water in the Well. The delivery pipe is provided with a check valve 18 to prevent the back-flow of the water.

under "pressurein a continuous flow by the same .operationto the receiving means 21. I

In this device the motor 22 may be mounted I above the centrifugal pump, driving the latter and the lift'pump bya' direct line shaft connection. i

In the utilization of myinvention, wells maybe sunk at such locations as are suitable .and such that the flow of water from the .vided as are required by the needs of different localities. 4

In operation the water is pumped directly from the well into the force pumping element of the system from which it is delivered under pressure in the same continuous operation, directlyinto the receiving and delivering medium employed to deliver the water to the distributing branches. I

Owing-to the arrangement and operatlon above described, my invention makes it pos- I sible to dispense with the necessity of pumppump receiving the" water under pressure I therefrom and leads to any suitablebranch ing to a large central reservoir from which the water is distributed by natural flow or by pumping from-a central station and'also enables the large trunk lines necessarily employed with the central distributingstation,

system to be dispensed with. I

Any. desired form of well pump, force pump. and motive power device may be employedand my invention does not reside in theparticular construction of such mechanisms.
